Description

TECHNICAL FIELD

[0001] The utility model relates to the field of evaporation technology, concretely relates to an evaporation device for improving utilization rate of evaporation boat. BACKGROUND

[0002] The functional current collector has a multilayer composite structure of "high polymer intermediate layer + conductive metal layer", and can provide a large resistance to cut off or reduce the short-circuit current in a short time through fusing and insulation when a short circuit occurs in the battery, thereby effectively preventing thermal runaway of the battery and improving the safety of the battery. The base material of the functional current collector is a high polymer film, and the copper plating and aluminum plating are realized by using a winding plating film process. In order to ensure the efficiency, the composite aluminum current collector is mostly plated with aluminum by evaporation. In order to ensure the production of long meters of aluminum plating, the aluminum evaporation is performed by resistance heating of an evaporation boat, and an aluminum wire coil is continuously and stably fed to the evaporation boat at high temperature. After the aluminum wire is melted, stable aluminum vapor is deposited and attached to the high polymer film flexible material.

[0003] After the aluminum wire sent by the wire feeding mechanism reaches the fixed position on the surface of the evaporation boat, the aluminum wire is melted to generate aluminum vapor. However, as the evaporation continues, the evaporation boat will be etched to form pits and cracks at the landing point of the aluminum wire under the action of the molten aluminum at high temperature. During the process of generating high temperature by resistance heating of the evaporation boat, the resistance of the position with pits and cracks will change, causing the heating temperature of the evaporation boat in the region to be uneven. The aluminum liquid is prone to splashing at the position with uneven cold and hot temperatures, resulting in poor appearance of the plated film product. In addition, the pits and cracks formed on the evaporation boat reduce the spreading area of the aluminum liquid on the surface of the evaporation boat, affecting the evaporation efficiency of the evaporation boat. When the corrosion of the pits and cracks is serious, the function of the evaporation boat will be seriously reduced, resulting in failure of the evaporation boat. TECHNICAL SOLUTION

[0037] The utility model mainly aims at the problem of existing functional current collector evaporation coating, in combination with current coating equipment and process, a kind of evaporation device is proposed;In the embodiment, take functional aluminum current collector evaporation aluminum coating as an example, and the metal wire therein is aluminum wire;The utility model can effectively improve the utilization of evaporation boat, and can help to stabilize evaporation coating, and improve evaporation efficiency.

[0038] As shown in Figure 2 As shown in the figure, rotary device 8 includes rotating surface 9, and rotating surface 9 is provided with positive evaporation electrode mounting port 10 and negative evaporation electrode mounting port 11, and the connecting pipelines of positive evaporation electrode 1 and negative evaporation electrode 3 are respectively led out from positive evaporation electrode mounting port 10 and negative evaporation electrode mounting port 11.

[0039] In some embodiments, positive evaporation electrode 1 and negative evaporation electrode 3 are provided with steps 12 at the bottom, and the periphery of evaporation electrode mounting port is provided with groove body, and step 12 is embedded in the groove body of evaporation electrode mounting port.

[0040] In some embodiments, the positive evaporation electrode 1 and the negative evaporation electrode 3 are respectively provided with a first clamping member 13 and a second clamping member 14. The first clamping member 13 is used to clamp and fix it to a first connecting portion 4 at one end of the evaporation boat 2, and the second clamping member 14 is used to clamp and fix it to a second connecting portion 5 at the other end of the evaporation boat 2. The clamping members are used to make the corresponding electrode more tightly and firmly connected to the end of the evaporation boat, and to maintain a relatively stable connection during rotation.

[0041] The rotating device 8 is connected to a drive motor 15. The drive motor 15 is used to make the rotating device 8 rotate clockwise by a first set angle and then counterclockwise by a second set angle. This oscillating rotation is repeated, thereby making the evaporation boat 2 oscillate and change its orientation. In conjunction with the wire feeding process of the wire feeding device, the area of ​​the position on the evaporation boat 2 that receives the wire is expanded.

Figure 5 As shown, the wire feeding adjustment unit includes a guide tube 16 and a guide tube angle adjustment structure 19. The guide tube 16 has a wire inlet 23 and a wire outlet 24. The wire feeding end of the wire feeding propulsion structure is connected to the wire inlet 23 of the guide tube 16, and the wire outlet 24 of the guide tube 16 is used to feed the wire to the evaporation space 6. The wire feeding propulsion structure can employ various wire feeding mechanisms in the prior art (not shown in the figure), which are used to push and transfer the metal wire in the wire spool 18 towards the evaporation boat 2.

Due to the change in the wire feeding pitch angle, the aluminum wire is fed to different positions on the evaporation boat 2, that is, the longitudinal wire feeding landing position of the evaporation boat 2 is different, and the etching position of the evaporation boat 2 changes from a point to a line, thereby extending the erosion etching resistance life of the evaporation boat 2.
